3. AlphaDisc™ CLD Controller Installation
The AlphaDisc™ CLD controller can be supplied as part of a filtration system or as a standalone device.
The controller is installed on a bracket and can be easily removed by pushing it up. If the controller is supplied as a
part of a filtration system, the controller is already installed and connected.
To disassemble the installed controller:
1. Disconnect all cables and pipes (see 3.3 AlphaDisc™ CLD Terminal Blocks Connections and 3.4 AlphaDisc™ CLD
DP Sensor Connections).
2. Push the controller up to remove it from the bracket.

3.1 INSTALLATION ON A POLE
If the AlphaDisc™ CLD controller is supplied separately, it can be installed on a pole using a plate and clamps (not
included).
Instructions:
1. Mount the 100x120 mm plate on the pole using clamps (minimum dimensions).
2. Remove the controller from the bracket (see Figure 3: Removing the AlphaDisc™ CLD controller from the bracket).
3. Tighten the bracket to the plate using 4 screws.
4. Attach the controller to the bracket. Press the controller until you hear “click”.
3.2 INSTALLATION ON A WALL
If the AlphaDisc™ CLD controller is supplied separately it can be mounted on a wall using fasteners (not included).
Instructions:
1. Determine mounting height for easy viewing and access.
2. Remove the controller from its bracket (see Figure 3: Removing the AlphaDisc™ CLD controller from the bracket).
3. Attach the bracket to the wall. Level the bracket by using a water level.
4. Mark the location of the bracket holes on the wall (see fig. below).
5. Using a drill, install 4 wall anchors in the marked locations. Attach the bracket to the wall. Tighten the mounting
screws into the anchors.
